CBT is required of nurses and midwives seeking UK registration who were trained outside of the European Economic Area.

Nursing in the UK is made up of separate and distinct fields of practice. The UK NMC CBT is a multiple-choice online exam for overseas nurses to get the nursing registration in the UK. Nurses can attend the CBT at a Pearson VUE test centre available in most of the countries around the world. The CBT comprises 120 multiple-choice questions with time limit of 4 hours to answer it.
